COPY-HOLDER FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 434,356, dated August 12, 1890.

Application tiled May 26,1890. Serial No 353,198. (No model.)

To aZZ whom, it may concern: l

' Be it knownthat we, MARTIN L. PIPES and EMILE F. PERNOT, of Corvallis, in the county of Benton and State of Oregon, have invented a new and Improved Copy-Holder for TypelVriting Machines, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved copy-holder specially designed for use on type-writing machines, which is simple and durable in construction, permits of readily inserting and moving the copy, andiseasily applied and conveniently arranged to facilitate the reading of the lines. The invention consists of a casing adapted to be .fastened to the carriage or other part of the machine, andl provided with a slot in its inclined front,`rollers journaled inthe said casing and between which passes the copy, and a lever and ratchet mechanism for turning one of the said rollers in either direction.

The invention also consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims. Y

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the improvement as applied on a type-writing machine. Fig. 2 is an end view ofthe improvement. Fig. 3 is a front view of the improvement, and Fig. 4is a transverse section of the same.

The improved copy-holder A is provided with a casing B, adapted to be fastened to the front rail of the carriage C or other part o'f a type-writing machine D, of any approved construction. The casing B is provided with a front E, fastened to two ends'E and E2, each provided in its lower edge with a recess E2, adapted to fit onto the front'rail of the carriage C. A spring-pressed hook-lever E4 is fulcrumed on each end E and E2 near the respective notch E2 and adapted to engage or hook onto the rear of the front rail o t the carriage C, so as to fasten the casin g B in place.

Within the casing B are arranged two longitudinally extending rollers F and G, of which the roller F is mounted with its trunnions F loosely in an inclined slot E5, formed in the ends E and E2 of the casing B. A spring F2 presses on each of the trunnions F',

so as to force the roller F toward'or onto the copy placed betweend the rollers F and G. The other roller G is mounted with its trnnions G in fixed bearings in the ends E and E2, and the outer end of one of the said trunnions is provided with a ratchet-wheel G2, adapted to be engaged by a double pawl H on the end E of the casing B. A spring H presses on the said pawl H, soas to hold one of its pointed ends in contact with the teeth of the ratchet-wheel G2. The pawl H is fulcrumed on an arm I, loosely fulcrumed on the trunnion G', carrying the ratchet-wheel G2.

In the arm I is arranged a transversely-eze tending slot I', into which extends one arm J of a vbell-crank lever J, having its other arm J2eXtending downward on the front of the type-writing machine D to within a short distance of the keys, as is plainly illustrated in Fig. 1, so that the said arm J2 of the bellcrank lever J can conveniently be manipu' lated by the operator. The bell-crank lever J is mounted to turn on a stud J 3, secured to the front E oi' the casing B. A torsion-spring J 4 is fastened with one end of the said stud J 2 and connected at its other end to the said lever J so as to hold the latter in a normal position. In the front E is arranged a slot E6, in which is held an adjustable bolt K, which serves to limit the movement of the arm J of the bellcrank lever J, so that the copy is moved a certain distance when the bell-crank lever J is operated, as hereinafter more fully described. In the front E of the casing B is also arranged a longitudinally-extending slot El, through which the lines of the copy appear, so as to be conveniently read by the operator. The width of the slot E7 can be increased or diminished by a longitudinally-extending plate L, provided at each end with rearwardly-extending armsL, fulcrumed at L2 on the ends E and E2 of the casing B. By moving the plate L up or down the width of the slot E7 is increased or diminished, accoi-ding to the height of the reading-lines of the copy, so that one of the lines, or more, as may be desired, may appear through the slot E7 when the device is used.

In order tohold the roller G in place after IOO it has been moved, a spring-pawl G3 is provided, secured to the end Ev and engaging the ratchet-whcel G2, as is plainly illustrated in Figz. In order to guide the copybetween the rollers F and G, a longitudinally-extending plate Es is provided, curved in S shape, as is plainly shown in Fig. 4, and extending from near the top of the roller G upward and rearward, as is plainly indieatedin the figure mentioned. A segmental plate E9 is also fastened between the ends E and E2 in front of the roller F, the said plate extending from the top of the roller G at its front to the lower edge of the slot E7. An inverted-U-shaped plate N extends from one end E to the other end E2 of the casing and passes with its downward end close to the roller F, thus forming on its rear end a passageway with the plate E8 for the introduction of the copy, and also forming on its front end with the plate L a passage for the paper after it leaves the rollers F and G. The paper in passing over the top rounded part of the plate N is guided rearward.

The operation is as follows: The casing B is fastened to the front rail of the carriage C in the manner previously described, so that the casing moves with the carriage on the top in the usual manner. The notches EB in the ends E and E2 are so arranged that when the casing is secured on the carriage the front E extends in an inclined position, so that the reading-lines on the copy can be conveniently read by the operator, said lines appearing through the slot E7. The copy is placed onto the longitudinally-extending plate E3, so that its lower edge passes between the rollers F and G. The operator by then moving the arm J2 of the bell-crank lever J tothe left causes the arm I to swing downward, so that the ratchet-wheel G2 is turned by the action of the pawl H. This movement of the ratchet-wheel G2 causes a like movement of the roller G, so that the copy is fed forward between the rollers F and G onto the plate E9, which guides the copy upward over the longitudinal curved plate N, so that the readingmatter appears through the slot E7, the width of which is regulated by the plate L, as previously described. Vhen the operator has copied to theend of the line appearing in the slot E7, then he moves the arm J2 of the bellcrank lever J to the left, so that the arm I is again swung downward to turn the roller G, as before described, to further feed the copy forward to bring the next line into the slot E. The return-movement of the lever J, as well as the arm I, is always accomplished by the action of the torsion-spring J 4. By adj usting the bolt K in the slot E the movement of the roller G is regulated, so that the copy is fed more or less according to the height of the lines el' the :reading-matter or distance between lines. to turn the copy backward, so as to compare already-copied matter with the type-written copy, then he changes the pawl Il, so that the \Vhen the operator desires.

other arm of the latter engages the ratchetwheel G2.` By then moving the lever J, as previously described, t-he roller G is turned in an opposite direction and the copy moves backward until the desired reading-matter appears in the slot E7. As the entire copyholder is held on the carriage C, it moves with the latter longitudinally and is swung upward with the carriage when the operator desires to examine the type-written copy. Thus it will be seen that the copy is immediately in front of the eyes of the operator and only the line to be copied is in view. The next line is brought into view by a simple and quick movement of the lever without leaving the key-board, as the arm J2 extends te within -a short distance of the said key-board.

Having thus described our invention, we

claim as new and desire to secure by Letters Patentl.
